About OtoBlade
OtoBlade is a focused listening-practice player: it turns any foreign-language audio into sentence-by-sentence practice you can repeat, shadow, dictate, and review. No account is required, and your learning material stays on your devices.
FAQ
Which audio formats are supported?
Common audio formats (m4a, aac, mp3, etc.) import directly; non-m4a is transcoded automatically. Audio can be extracted from video files (mp4/mov) at no cost.
Is my data safe?
All audio and segments stay on your own device. No account is required and your audio is never uploaded. Exporting and restoring backups is always free.
What is the difference between Standard and Pro?
Standard includes full core playback, manual and subtitle slicing, segment editing, looping, dictation, shadowing, backup, and built-in learning courses. Pro adds more efficiency tools for high-frequency practice. See the feature comparison.
How does Wi-Fi cross-screen dictation work?
Enable the server in Settings, connect phone and computer to the same Wi-Fi, then open the shown URL (or scan the QR) in your computer browser to type along on the big screen — synced in real time.
How do I back up my data?
Export an .otoblade backup (optionally with audio) in Settings, and import it on a new device to restore. Backup and restore are always free.
